A duplex in Rosemeadow costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Campbelltown City Council approvals, construction and subdivision under one fixed-price contract.
Rosemeadow Duplex Construction
A duplex in Rosemeadow works on most blocks, helped by Campbelltown's lower duplex minimum. Lots run 500 to 750m2 of R2 against a 500m2 minimum under the Campbelltown DCP, so most qualify. On a $800K to $1.05M market with the Marketplace and local schools anchoring the suburb, a Torrens-title duplex on a qualifying block is a sound investor or family play.
The ground is Class H reactive clay, so footings are engineered off geotech and the slab detailed to suit on both dwellings, because that soil moves with moisture. The 1980s to 1990s brick-veneer stock can carry asbestos on the earlier homes, so I confirm the era before demolition.
What I would check first on your Rosemeadow block: the area against the 500m2 minimum, the reactive-clay class once geotech is back, and the frontage.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you what it carries.
Buildana manages the full duplex development process in Rosemeadow — from feasibility assessment and architectural design through to DA or CDC approval, and fixed-price construction to dual handover. One builder, one contract, two homes.

How It Works
From First Call to Final Key
Site visit, title search, and planning assessment for your Rosemeadow block. We check lot dimensions against Campbelltown City Council's minimum (500m² under Campbelltown Sustainable City DCP 2024), review overlays, drainage, access, and services.
⏱Design has to satisfy four audiences at once: Campbelltown City Council, the future buyer or tenant, the certifier, and you. Each pull in a different direction — our job is to land plans that work for all four.
⏱We lodge and chase your approval — DA through Campbelltown City Council for most duplexes, or CDC where eligible. R2 Low Density predominant zoning in Rosemeadow.
⏱Building both sides in parallel halves the loan interest holding cost vs sequential builds. Bulk material orders for cabinetry, tiles, fixtures cut unit cost.
⏱Strata or Torrens title subdivision completed. Separate OCs, individual metering, 6-year structural warranty per dwelling.
⏱Quality Promise
Our Rosemeadow duplex projects run from feasibility to subdivision under one builder. Fixed price, dual handover, full compliance.
